Disease pressure remains relatively low across the state as cooler temperatures continue for a few more days. Main field activities this past week included fungicide applications in corn and soybeans, second- and third-cutting hay, and tiling in harvested wheat fields. Keep reading for region-specific details from Ohio State University Extension Educators and Specialists.
Central & West Central – Ryan McMichael of OSU Extension Mercer County reported that soybean has reached the R6 growth stage (full seed) and is in good condition despite weed escapes. So far, the most problematic weed species are volunteer corn, velvet leaf, giant ragweed, and waterhemp. Corn is also in good condition and early planted fields have reached dent growth stage (R5).
Southeast – OSU Extension Educator Jordan Penrose of Morgan County shared that both corn and soybean are in fair condition. Weed and pest pressure remain low, but the area is still extremely dry, especially south of I-70. Second-cutting hay is being made, but reported yields are low. Continued dry conditions haven also taken a toll on pasture fields, as area growers start to feed hay.
Northeast – Lee Beers of OSU Extension Trumbull County reported that corn and soybean are in good condition with adequate soil moisture levels. Soybean growth stage ranges from R2 (full bloom) to R6 (full seed), and corn is anywhere between R2 (blister) and R4 (dough). Disease pressure is low, with no signs yet of white mold in soybean, and low incidence and severity of tar spot and northern corn leaf blight in corn so far. Severe storms however damaged property and lodged several hundred acres of corn, with lodging severe in some instances.
